Tech Support Forum - View Single Post - Random online disconnects "Your Network Cable Unplugged"

Hi guys.

I'm experiencing a similar (if not the same) problem.

Current config is
- 3COM Office Connect WE754G72E Router/ADSL Modem/WLAN.
Set as DHCP server, with leases assigned forever (was daily but I changed it while trying to solve this problem)
- PC XP SP2 with Realtek RTL8139 onboard LAN.
- Laptop XP SP2 with 3COM 54Mbps WLAN PC Card.
- Laptop XP SP2 £Com EtherlinkIII PC Card.

All machines upgraded to SP2 simultaneously, and indeed possibly foolishly :p

I'm not sure if this started happening directly as a result of installing SP2 but it was around that time.

Every 10 minutes or so on the wired connections, the network notification balloon pops up telling me that the cable is unplugged. If I go into the event viewer there are three events:

1) INFO - TCPIP - 4201 - The system detected that network adapter \DEVICE\TCPIP_{4F313558-8338-4E25-A690-C3F4DBE75CEE} was connected to the network, and has initiated normal operation over the network adapter.
2) As 1.
3) WARNING - DHCP - 1003 - Your computer was not able to renew its address... yada yada yada

The connection picks back up again within a few seconds but it's enough to throw out one or two more "sensitive" pieces of sotware that have to be restarted to pick up the link again.

OK - I've just run a couple more tests, I initially thought it was only the wired connections that drop but it's not, the difference seems to be that the WLAN doesn't throw the DHCP warning event and doesn't trigger notification.

As an added bonus, in my case it seems that the one "sensitive" piece of software is also the cause of my woes or at least the catalyst :( If I don't start eDonkey, no problem, with it running and a list of files to download, the LAN trips.

I would guess that my router doesn't like the throughput or the number of connections it's being asked to handle.

I'll play some more and update if my situation changes.
